Introducing the Chorus Brigade: A Timeless Icon of Japanese Modulation
In 1976, a groundbreaking gray bucket-brigade stompbox entered the music scene, forever altering its sonic landscape with its lush chorus and mesmerizing vibrato. Fast forward to the present day, and Astra's Brigade Chorus mode pays homage to this iconic unit by delivering the most comprehensive circuit emulation, complete with its distinctive preamp section that produces authentically thick, saturated sounds. This innovation allows musicians to wield subtle ripples of analog texture and tone, infusing their playing with chewiness, shimmer, and motion.
Venturing into the realm of studio classics, Astra brings forth the Flanger/Doubler, a nod to the late-'70s rackmount flanger/doubler celebrated for its stunning whoosh effects and organic thickening. Astra's Flanger/Dblr effect stands as the sole end-to-end circuit emulation of this rare unit, faithfully reproducing its original features. The result is an accessible tool that places impossibly dense, complex flanging and doubling capabilities right at the musician's fingertips.
For those seeking the nostalgic tremolo of '60s American amplifiers, the Trem 65 emerges as the go-to choice. A faithful emulation of the optical tube-driven tremolo, Trem 65 captures the deep, undulating essence of vibe that defined that era. From shimmering ripples to choppy mayhem, every dynamic detail is meticulously replicated in UA style. The interaction between the light source photoresistor and the 12AT7 driver tube is faithfully reproduced, and users can further explore and customize their trem textures with variable sine and square wave settings.
What sets Astra apart is its Dual Stereo Modulation Engines, powered by the UAFX engine. This unique feature enables separate stereo instances of each modulation effect, simulating the experience of having two bucket-brigade hardware units or dual tremolo circuits running simultaneously. The result is a full stereo spread of complex, jaw-dropping textures that opens up endless possibilities for creative expression.
As a state-of-the-art stompbox, Astra Modulation Machine incorporates modern, high-powered features such as studio-grade conversion, dual-processing engines, additional downloadable effects upon registration, Live/Preset modes, true/buffered bypass,* and silent switching. With these tools at your disposal, Astra empowers you to unleash your creativity and paint your musical masterpiece.
